WRENCH.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed October 12, 1909. Serial N 0. 522,293.

To all whom it may concern:

Be it known that I, HOMER J. MUNDAY, a citizen of the United States,residing at Carterville, in the county of Jasper and State of Missouri,have invented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the the wrench to engage nuts of varying sizes;

A further ob ect is to so arrange the aws of the wrench as to permit ofeasy movement of the wrench in close places.

A further object is to provide means for attaching the jaw sections tothe handle section and a further object is to provide means for holdingthe handle section against inde- (Ither objects and advantages will behereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1is a side elevation of the wrench. Fig. 2 is an edge view thereof partlyin section. Fig. 3 is a longitudinal sectional view through the wrench.Fig. A is an end elevation of the handle section removed from thewrench. Fig. 5 is an edge elevation of a clip employed for securing thehandle section to the jaw section, and Fig. 6 is a plan view thereof.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates thestationary jaw of my improved wrench, the shank 2 of which is hollow toreceive the solid shank 3 of the movable jaw 4:, the meetings faces ofsaid jaws being set at an angle to the axis of their respective shanks,whereby the end of the wrench may be introduced into a small space andengaged with the nut.

Positioned at the lowerend of the shank 2 is a handle section 5, whichhandle is provided with an orifice 6 through which the threaded end ofthe shank 3 extends, the threads 7 upon the shank 3 engaging threads 8adjacent the upper end of the section 5,

the threads 8 being placed in an opening in a partition 9 formedintegral with the handle section.

The handle section 5 is adapted to be rotated independently of the shank2, thereby causing the shank 3 and jaw carried thereby to move inwardlyor outwardly, said handle section being held in engagement with theshank 2 by means of clips 10, the upper ends of which engage the outerfaces of the shank 2 and are attached thereto by means of screws 11,while the lower ends of the clips are substantially channel shaped toform recesses 12, into which extends a circumferential rib 13 at theupper end of the handle section 5, said rib section extending inwardly.

The lower end of the handle section 5 is provided with a removable cap14, whereby ready access may be had to the interior of the handle, sothat a nut 15 may be readily applied to the lower end of the shank 3,said nut preventing the shank 3 from being entirely removed from theshank 2 by the nut 15 coming in contact with the lower face of thepartition in the upper portion of the handle section, but should it bedesired to remove the shank 3, the nut 15 may be removed and the handlesectionrotated until the'threads 7 are disengaged from the threads 8,when the shank 3 may be drawn out of the shank 2.

After the jaws of the wrench have been moved into engagement with thenut or other object, they are securely locked against separating byproviding a plurality of sockets 16 in the upper end of the handlesection 5, into which is adapted to be introduced the lower end of alocking pin 17, said pin being introduced through keepers 18 and 19 onthe shank 2, the keeper 19 being removably secured to the shank, wherebythe pin may be readily attached to the shank. The pin 17 is normallyheld in its lowered position by means of a spring 20, the lower end ofwhich engages awasher 21, carried by the pin 17, while the upper endthereof engages the keeper 19, whereby when said pin is raised, thespring will be compressed, and will exert tension against the pin andlower the same when the pin is released, a head 22 being provided at theupper end of the pin, whereby the pin may be readily grasped andelevated when desired.

In assembling the parts of the wrench,

i. A in... LLMM i the clips are engaged with the rib in the handlesection and the shank 2 then entered between the upper ends of the clipsand secured thereto-by means of screws 11, thereby holding the handlesection securely in engagement with the shank 2, and at the same timepermitting said handle section to be rotated. The shank 3 is thenintroduced through the opening 23 in the shank 2 until the threads onthe shank 3 come into engagement with the threads 'in the partition 9,when the handle section is rotated until the jaw 4 is moved intoengagement with the j aw- 1, thus bringing the lower end of the shank 3adjacent the lower end of the handle section. The nut 15 is thenturnedonto the lower end of the shank 3 and the cap 14 introduced onto thelower end of the handle section 5, when the wrench is ready for use.

In applying the wrench to use, the pin 17 is elevated and the handlesection 5 rotated until the jaw 4 is properly adjusted to receive thenut, when the pin 17 is released and permitted to enter one of thesockets 16, thereby holding the movable jaw in its adjusted position.When the handle section 5 is being rotated, the shank 2 is grasped inone hand and held in a fixed position while the handle section isrotated with the opposite hand and inorder to provide a firm grip forthe handle section, the exterior portion thereof is provided with aplurality of spirally disposed ribs 24 by which construction the handlesection may be positively rotated even when the hand of the operator iscovered with grease or when wearing a glove.

It will thus be seen that I have provided a very cheap as well as strongand durable form of wrench and one that can be quickly applied to use.It will further be seen that in view of the arrangement of the jaws ofthe wrench, the end ofthe wrench may be introduced into a small spaceand engaged with an object and be readily operated to turn the objectand it will further be seen that the jaws of the wrench may be securelylocked in their adjusted positions.

What I claim is: q

1. In a wrench, the combination with a fixed jaw, a shank attachedthereto and having an opening therethrough, a movable shank extendingthrough said opening and a jaw on said movable shank, the lower end ofsaid movable shank being threaded; of a handle section having an orificetherein, a

partition adjacent the upper end of said handle section, having threadstherein to engage the threads on the movable shank,

a rib within the upper end of said handle section, clips secured to saidhollow shank and having means at their lower ends to engage said ribwhereby the handle section lwill be held in engagement with the hollowshank and permitted to rotate and means to lock said handle sectionagainst rotation.

' 2. A wrench, comprising a fixed jaw, a

shank entering the hollow shank, a jaw at the outer end of said movableshank, the

inner end of said shank being threaded, a handle section having athreaded partition adapted to receive'the threaded portion of the shank,an inter-iorly disposed rib at the upper end of the handle section,clips having recesses in their lower ends adapted to. receive said riband means to attach the I hollow shank carrying said jaw, a movable
